Analog modelling is not Verilog's forte, but it can be done.  In fact, if you
order the mixed-signal product with Analog Artist, you get some analog
behavioral models in Verilog.

I don't claim to be a Verilog modelling expert, but I once wrote a vco model
in Verilog to prove to some people that it could be done.

To pass an analog value into a Verilog module, you have to create a 64-bit wire
port.  You then use system functions like $bitstoreal to convert the wire at
the port to a real number inside the module.  Once you have real numbers inside
the module, you can do anything you want.
